It can be difficult to clean the uneven surfaces of the teeth, which leaves these areas vulnerable to cavities. The dentist can attach sealants to teeth to protect against decay. These sealants are tough coatings that block plaque from living in these hard-to-clean areas.
The teeth must be cleaned and examined first. After that, the dentist will coat the teeth with sealant, and that will bond to each tooth and harden. This treatment only takes a few minutes for each tooth. Sealants are extremely durable and long-lasting methods of preventing tooth decay and other dental problems.
